FLOOR-SURFACING MACHINE.

Specification of Letters Patent.

Application filed January 31, 1910.

Patented Dec. 27, 1910.

Serial No. 541,034.

To all whom it may concern:

Be it known that I, VILLIAM E. lVAnNnn, citizen of the United States,residing at Houston, in the county of Harris and State of Texas, haveinvented certain new and useful Improvements in Floor-SurfacingMachines, of which the following is a specification.

My invention relates to new and useful llnPl'OYQlDBntS in floorsurfacing machines.

The object of the invention is to provide a machine of the characterdescribed pivotally mounted upon supporting carriers and carrying anabrading roller which may be forced. into contact with the floor tobesmoothed, or withdrawn from said contact by operating the machine uponits pivoted support.

With the above and other objects in view my invention has particularrelation to certain novel features of construction and operation anexample of which is given in this specification and illustrated in theaccompanying drawings, wherein Figure 1 is a side elevation of themachine. Fig. 2 is a plan View thereof.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, the numeral1 refers to the framework of the machine which is composed of suitableside members connected by cross braces. These side members extendrearwardly and terminate in suitable handles 2 for guiding the machine.

The machine is mounted on two conveyers 3 and 4: which are mounted upona transverse shaft 5 and near the center thereof on either side. Thisshaft 5 operates in suitable bearings in the side members and is locatedslightly in front of the longitudinal center of the frame. The conveyorsare located near the center of their shaft so as to pivot the frame workin such a manner that it may be teetered either laterally orlongitudinally, and the conveyer 3 is rigidly secured to said shaftwhile conveyer 1 is loosely mounted but secured against lateral movementthereon. hen it is desired to turn the machine around it may easily betilted until it rests only on conveyer 1 and its forward movement thusstopped, thus providing for more case in turning.

Upon the machine frame I have mounted a motor 7 of the ordinary type,Whoseshaft carries spur gear 8 which meshes with spur operated thereby.

gear 9 rigidly mounted on the transverse shaft 10 rotatable in suitablebearings upon the side members 1. Upon shaft 10 I have mounted a wormgear 11 designed to mesh with a similar worm gear 12 carried upon thedrive shaft 13. This drive shaft carries a bevel gear 11 at its free endfor a purpose presently to be described. Upon shaft 5 I have secured adouble bevel gear 15 slidable but not rotatable thereon and the bevelgear 11- projects between the members thereof and one of said members isnormally held in mesh with said gear 1 through the operation of spring16, as shown in 2. \Vhen it is desired to throw the machine out of gearthe double gear wheel is moved on its shaft until neither member mesheswith gear 11 and when it is desired to reverse the machine gcar 15 isfurther moved till its other member is brought into mesh with gear 11.This movement of the gear 15 is accomplished by means of the bell crank17 pivoted to the side member 1 and one arm of which engages with saidTo the other arm of this bell crank I have attached a rod 18 leadingback to one of the handles of the machine so as to be readilymanipulated by the operator. By a proper manipulation of the rod 18, itis readily obvious that the machine may be given forward or reverse gearor may be thrown entirely out of gear. Upon shaft 10 1 have also mountedthe spur gear 19 which meshes with a similar spur gear 20 carried uponthe outer end of transverse shaft 21. This shaft 21 is rotatable inremovable bearings, secured in sockets in the forward ends of sidemembers 1. Upon the shaft 21 I have secured an abrading roller 22, whichcomprises a metallic cylindrical body secured in place about said shaftby means of radiating arms 23, extending from said shaft to the cylinderbody. This cylinder is covered by sand paper or some other suitableabrading surface.

The numeral 21 refers to a hood which embraces the abrading roller andis de signed to collect the dust and cuttings of the roller and conveythe same to dust pipe 25 which communicates with the blow fan 26 whichis mounted upon the motor 7 and From the casing of this fan a dischargepipe 27 leads and discharges into receptacle 28.

Near the rear end of the frame I have provided a caster 28 which isvertically movable in its bearings. The rear side of the shank of thiscaster has gear teeth which mesh with the gear teeth of gear wheel 29centrally located on shaft 30. This shaft has an arm 31 extendingtherefrom to the free end of which rod 32 is attached. This rod providedwith a handle 33 through which it is operated and when it is desired todepress the caster and elevate the rear end of the machine frame thisresult may be readily accomplished through the proper manipulation ofthe rod 32, and by the elevation of the rear end of the frame theabrading roller is held in contact with the surface to be cut away. Whenthe handle 33 is released the rear end of the frame descends and theabrading roller is elevated away from the surface.

A surfacing machine constructed as described and shown will be found tobe sim ple and easy to construct and operate and will efficientlyaccomplish the purpose for which it was designed.

hat I claim is:

1. In a floor surfacing machine the combination with a pivotallymounted.support ing frame of an abrading roller carried by one endthereof; traction wheels for said frame; a motor carried thereby andoperatively connected with the abrading roller; a transmission mechanismconnecting said motor with the traction wheels of said device wherebyforward or reverse movement may be imparted to the same; and a mechanismcarried by the end of the frame opposite to the abrading roller forelevating said end and depressing the roller end of the frame, saidmechanism including a vertically movable caster, and gear teeth carriedby the shank thereof, a gear wheel carried by the frame and designed tomesh with the teeth of the shank and a hand lever operatively connectedto said gear wheel whereby the same may be rotated and the caster movedvertically.

2. In a floor surfacing machine the combination with a pivotally mountedsupporting frame of an abrading roller carried by one end thereof;traction wheels for said frame; a motor carried thereby and operativelyconnected with the abrading roller; a transmission mechanism connectingsaid motor with the traction wheels of said device whereby forward orreverse movement may be imparted to the same; and a mechanism carried bythe end of the frame opposite the abrading roller for elevating said endand depressing the roller end of the frame, said mechanism including avertically movable caster, and gear teeth carried by the shank thereof,a gear wheel carried by the frame designed to mesh with the teeth of theshank, a crank arm carried by the axle of the said gear wheel and a handlever operatively connected to said crank arm whereby the same may berotated and the caster moved vertically and the abrading roller held inpositive contact with the surface to be abraded.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
